Abstract:

This paper summarizes the working principle of laser particle size analyzer, and some experimental study can be made to monitor the number and size of abrasive particle in the oil of lubricant by the laser particle size analysis method. It obtains the particle size distribution of lubricant’s abrasive particle at different times, so the working status of the gearbox can be judged by it. At the same time, we can sum up the growth law of the largest abrasive particle and the minimum abrasive particle in the lubricant. So we can judge the abnormal wear time of device to achieve timely repair and maintenance of equipment. The results showed that the laser particle size analysis method can quickly and efficiently monitor the particle size distribution of abrasive particle in the lubricant. This can provide the advantageous basis for judging the running state of the bulldozer’s gearbox, consequently this can effectively prevent equipment failure.
